InC-Ops-Notifications - This email list is used by InCommon Operations to send important notifications about modifications to the metadata generation system, service interruptions, and any other important technical announcements as they occur. All official InCommon Site Administrators are automatically subscribed to this list as a requirement to participation in InCommon services. Any other technical contacts may also subscribe.

Metadata-DIFF - This email list sends out a daily diff of two varieties. When we test the system, we publish a diff comparing the current production metadata with the test system. This prod-test diff will be generated during the published testing period. The prod-prod diff compares the previous version of the production metadata with the newly issued version of the production metadata. A diff will be generated during each signing event, so you can expect multiple diffs in a single day if we sign the metadata multiple times. These diffs are also archived.
